Toyota Corolla (E210): Toyota Safety Sense 3.0

The Toyota Safety Sense 3.0 consists of the driving assist systems and contributes to a safe and comfortable driving experience:

WARNING

■Toyota Safety Sense 3.0

The Toyota Safety Sense 3.0 operates under the assumption that the driver will drive safely, and is designed to help reduce the impact to the occupants in a collision and assist the driver under normal driving conditions.

As there is a limit to the degree of recognition accuracy and control performance that this system can provide, do not overly rely on this system. The driver is solely responsible for paying attention to the vehicle's surroundings and driving safely.

■For safe use

• Do not overly rely on this system.

  The driver is solely responsible for paying attention to the vehicle's surroundings and driving safely. This system may not operate in all situations and provided assistance is limited.

  Over-reliance on this system to drive the vehicle safely may lead to an accident resulting in death or serious injury.

• Do not attempt to test the operation of the system, as it may not operate properly, possibly leading to an accident.
• If attention is necessary while performing driving operations or a system malfunction occurs, a warning message or warning buzzer will be operated. If a warning message is displayed on the display, follow the instructions displayed.
• Depending on external noise, the volume of the audio system, etc. it may be difficult to hear the warning buzzer. Also, depending on the road conditions, it may be difficult to recognize the operation of the system.

■When it is necessary to disable the system

In the following situations, make sure to disable the system.

Failure to do so may lead to the system not operating properly, possibly leading to an accident resulting in death or serious injury.

• When the vehicle is tilted due to being overloaded or having a flat tire
• When driving at extremely high speeds
• When towing another vehicle
• When the vehicle is being transported by a truck, ship, train, etc.
• When the vehicle is raised on a lift and the tires are allowed to rotate freely
• When inspecting the vehicle using a drum tester such as a chassis dynamometer or speedometer tester, or when using an on vehicle wheel balancer
• When the vehicle is driven in a sporty manner or off-road
• When using an automatic car wash
• When a sensor is misaligned or deformed due to a strong impact being applied to the sensor or the area around the sensor
• When accessories which obstruct a sensor or light are temporarily installed to the vehicle
• When a compact spare tire or tire chains are installed to the vehicle or an emergency tire puncture repair kit has been used
• When the tires are excessively worn or the inflation pressure of the tires is low
• When tires other than the manufacturer specified size are installed
• When the vehicle cannot be driven stably, due to a collision, malfunction, etc.

Sensors used by Toyota Safety Sense 3.0

Various sensors are used to obtain the necessary information for system operation.

■ Sensors which detect the surrounding conditions

1. Front radar sensor
2. Front camera

WARNING

■To prevent malfunction of the radar sensors

Observe the following precautions.

Failure to do so may lead to a radar sensor not operating properly, possibly leading to an accident resulting in death or serious injury.

• Keep the radar sensors and radar sensor covers clean at all times.

Clean the front of a radar sensor or the front or back of a radar sensor cover if it is dirty or covered with water droplets, snow, etc.

When cleaning the radar sensor and radar sensor cover, use a soft cloth to remove dirt so as to not damage them.

Type A

Type B

1. Radar sensor
2. Radar sensor cover

• Do not attach accessories, stickers (including transparent stickers), aluminum tape, etc. to a radar sensor or radar sensor cover and their surrounding area.
• Do not subject a radar sensor or its surrounding area to impact.

  If a radar sensor, the front grille, or front bumper has been subjected to a impact, have the vehicle inspected by your Toyota dealer.

• Do not disassemble the radar sensors.
• Do not modify or paint the radar sensors or radar sensor cover, or replace them with anything other than Toyota genuine parts.
• In the following situations, recalibration of the radar sensors will be necessary. For details, contact your Toyota dealer.
  • When a radar sensor is removed and installed, or replaced
  • When the front bumper or the front grille has been replaced

■To prevent malfunction of the front camera

Observe the following precautions.

Failure to do so may lead to the front camera not operating properly, possibly leading to an accident resulting in death or serious injury.

• Always keep the windshield clean.
  • If the windshield is dirty or covered with an oily film, water droplets, snow, etc., clean the windshield.
  • Even if a glass coating agent is applied to the windshield, it will still be necessary to use the windshield wipers to remove water droplets, etc. from the area of the windshield in front of the front camera.
  • If the inner side of the windshield where the front camera is installed is dirty, contact your Toyota dealer.
• Do not attach stickers (including transparent stickers) or other items to the area of the windshield in front of the front camera (shaded area in the illustration).

1. Approximately 1.6 in. (4 cm)
2. Approximately 1.6 in. (4 cm)

• If the part of the windshield in front of the front camera is fogged up or covered with condensation or ice, use the windshield defogger to remove the fog, condensation, or ice.
• If water droplets cannot be properly removed from the area of the windshield in front of the front camera by the windshield wipers, replace the wiper insert or wiper blade.
• Do not attach window tint to the windshield.
• Replace the windshield if it is damaged or cracked.

  If the windshield has been replaced, recalibration of the front camera will be necessary.

  For details, contact your Toyota dealer.

• Do not allow liquids to contact the front camera.
• Do not allow bright lights to shine into the front camera.
• Do not damage the lens of the front camera or allow it to become dirty.

  When cleaning the inside of the windshield, do not allow glass cleaner to contact the lens of the front camera. Do not touch the lens of the front camera.

  If the lens of the front camera is dirty or damaged, contact your Toyota dealer.

• Do not subject the front camera to a strong impact.
• Do not change the position or orientation of the front camera or remove it.
• Do not disassemble the front camera.
• Do not modify any parts around the front camera, such as the inside rear view mirror or ceiling.
• Do not attach accessories which may obstruct the front camera to the hood, front grille, or front bumper. For details, contact your Toyota dealer.
• If a surfboard or other long object is to be mounted on the roof, make sure that it will not obstruct the front camera.
• Do not modify or change the headlights and other lights.

WARNING

■Front camera installation area on the windshield

If the system determines that the windshield may be fogged up, it will automatically operate the heater to defog the part of the windshield around the front camera.

When cleaning, etc., be careful not to touch the area around the front camera until the windshield has cooled sufficiently, as touching it may cause burns.
